IPC: G06F12/10
Filed: 1994-03-10
Abstract: PURPOSE:To prevent respective CPUs (data processing parts) from performing different operations and to improve reliability by permitting a decoding processing only when a valid flag is set in a read instruction code. CONSTITUTION:When the valid flag is set in a directory part for the instruction code read from a buffer storage part 53, even it is possible that the instruction code from the buffer storage part 53 is to be judged as an erroneous hit later, the same contents are held in the buffer storage parts 53 of all the data processing parts 51 for the entry. In such a case, read from the buffer storage parts 53 of the respective data processing parts 51 to a decoder 54 is performed and simultaneously, the decoding processing of the instruction code by the decoder 54 is permitted in the decoding permission judgement parts 55 of the respective data processing parts 51. Thus, until hit/erroneous hit judgement is obtained after reading the instruction code from the buffer storage parts 53, the processing operations in all the data processing parts 51 become the same and the reliability of this data processor is improved.

Filed: 1984-03-02
Abstract: PURPOSE:To realize omission of various lines while a caller and a called party are in busy in either case where the caller and the called party are on the same line or on a different circuit by enabling detection with the same trunk. CONSTITUTION:A current, when a caller 1 is forming a loop, is converted into a voltage respectively by resistors 3, 4, 5, and 6, consequently and reduced to 7 and 8. The current then is displaced by digital data at an A/D convertor 9 and stored in a microcomputer 10. Afterward, an oscillating circuit 11 outputs a selective signal and a call signal to the called party, however, voltage values 7 and 8 are not fluctuated by AC cut coils 12 and 13 and an AC bypass capacitor 14, and a new loop is superposed because of HOOK OFF by the called party 2, thus the voltage values 7 and 8 are fluctuated. These values are read by the microcomputer at any time and detected. In the same way, the change in a HOOK condition of the telephone is all detected by the present system, thereby this circuit can cope with any situation irrespective of the same line talk or some other line talk.

IPC: B60T8/66
Filed: 1989-02-20
Abstract: PURPOSE: To stop a vehicle at the shortest distance even on a irregular road, by increasing the critical value of a wheel rotation condition by given quantity to a critical standard value, in at least one period of time intervals for increasing brake pressure in a control cycle halfway. CONSTITUTION: When a wheel rotation condition at the time of braking is measured, and a measured value exceeds a critical value, anti-lock control is performed as follows: a critical value is increased to a critical standard value SG, and successively is reduced with a time for reducing brake pressure in accordance with a slip and/or deceleration, and then increase the brake pressure again, and also preventing the excess of the measured value than the critical value. In this case, the critical value is suddenly increased by given fixed quantity SH-SC to the critical standard value SG, at the position of time t2 corresponding to at least one period of time intervals t2 -t1 for increasing the brake pressure in a control cycle halfway. Consequently the increasing process of the brake pressure is not interrupted even the vibration of an axle or the deceleration of a wheel rotation due to a road recess, etc., thus a vehicle can be stopped at the shortest distance.

Abstract: PURPOSE:To automatically apply a brake by an emergency brake even if a defect is generated in an oil side, by providing an emergency brake actuating valve actuated only in the full stroke of an air piston when the oil side detect is generated in brake boosters. CONSTITUTION:When a defect is generated in a system of oil pipes 5, an air piston 16 moves to its full stroke because an oil piston 17 in a brake booster 2 moves to the extream advance end. And the air piston 16, immediately before it is placed in the full stroke, actuates an emergency brake actuating valve 14 to be opened, causing an air signal pressure of an air signal pipe 12 to be released to the atmosphere through a pipe line 15. Then a relief valve 10 cuts off supply of air to spring brake chambers 7 from an air pipe 9, and the air supplied to said chambers 7 is released to the atmosphere through an air pipe 11 and the relief valve 10. As the result, a spring brake performs emergency action.

Title: Semiconductor laser device
Inventor: KONO TOSHIHIRO
IPC: H01S5/00
Filed: 1987-02-25
Abstract: PURPOSE:To prevent the interference caused by a plurality of light sources and fo prevent abnormal tracking, by forming a part of at least one end surface of a semiconductor substrate in a slant or curved shape with respect to the end surface of a laser-light emitting part, or by removing a part of the semiconductor substrate in a stripe shape. CONSTITUTION:A part of the end surface of a substrate 1 is slanted by 5 deg. or more with respect to the end surface of a laser-light emitting part or formed in a curved shape at the end surface of a laser device. The distance between an active layer 4 and the slant end surface or the curved end surface is made to be 50 mum or less. When these elements are used as a pickup light source for an optical disc, the primary reflected light, whose image is formed at the distance of about 50 mum from the active layer 4, is hardly returned to a pickup optical system at the end surface of the laser device. Therefore interference due to a plurality of light sources does not occur in the pickup optical system, and abnormal tracking is not yielded.

Abstract: PROBLEM TO BE SOLVED: To heighten the separation resistance without giving influence to the optical propagation characteristic of an optical waveguide, by making the effective refractive index of the optical waveguide at the lower part of an isolation mesa part larger than that of the optical waveguide other than the lower part. SOLUTION: The larger thickness of an InGaAsP active layer 3a and light shut-in layers 3b, 3c of an isolation mesa part 12 is made thicker than the layer thickness of each layer of a semiconductor laser (LD) part. With the layer thickness of an optical waveguide of the mesa part 12 thus made thicker than the other parts, an effective refractive index at this part becomes large, and the light shut-in effect of the optical waveguide is improved. The remaining film thickness of a p-InP clad layer 5 of the mesa part 12 can be made thin to 0.8μm from 1.2μm of conventional structure, for instance, and separation resistance of the mesa part 12 is increased in inverse proportion to the remaining film thickness of the p-InP clad layer 5, so that separation resistance can be heightened by 1.5 times.

Abstract: PURPOSE:To carry out electrolysis until monomethyl adipate and monomethyl dodecanedioate are practically used up when dimethyl thapsate is manufactured, by electrolytically condensing the compounds, by carrying out electrolysis for a fixed time, adding the former compound, and continuously carrying out electrolysis. CONSTITUTION:A mixture of monomethyl dodecanedioate with 0.5-2.0 times as much monomethyl adipate as monomethyl dodecanedioate by mole is electrolytically condensed in a soln. of alkali metallic salts of the compounds in methanol by a batch system for a fixed time. Monomethyl adipate is then added, and electrolysis is continuously carried out. Thus, a sudden voltage rise which makes the succession of electrolysis impossible is prevented in the latter half of electrolysis. Accordingly, dimethyl thapsate can be manufactured industrially advantageously.
